MODE 0F MAKING A BATTING on WEB EOE HAT-BODIES.

Specification of Letters Patent No; 3921,'idat'ed vSeptember 22, 1837. i i

same Shall be issued, has been assigned to us; and we do hereby declare that the following is a Afull and exact description of our improvements on the said machine, in-' cluding therein such references to the parts of the original machine as are deemed necessary to make our improif'ements fully.

known, and introducing them for this purpose only.

Our first improvement consists in the addition of a roller which is to press lightly upon the fur as it passes along the feed apron, previously to its entrance vbetween the feed rollers; Which roller has been found necessary to prevent the fur from being Vdrawn into thecards Without passing be-v tween the feed rollers, Which, from its lightness, may otherwise happen. This roller isy marked A, in the accompanying drawing.

Secondly, instead of the feeding rollers originally employed, we have substituted two rollers of iron, B, B, which are fluted from end to end, and which have been found to bring the fur upon the cards more equably and vevenly than heretofore.

Thirdly, we employ a covering of thin boards, or other suitable material, which oc cupies the position represented by the red line, C, in the drawing; thus covering the cards over their tops as far back as between the dofl'er and quick fancy; conforming the same, as far as practicable, to the shape of the space occupied by the cards when in place, and so as not to interfere with them when running.

Fourthly, we place a partition across the interior of the machine, in the situation represented by the vertical, red line D. This extends up from the bottom as near as possible to, andvbetween, the don'er and the quick fancy. By the aid of this partition we obtain a direct, equable and correct cur rent of air passing immediately upon, and

through, lall the cards to the quick fancy,.

Which, by means of this current of air,

throws the fur in small particles into' the-'ani Sixthly, we have added a receiving' board f shown on the' drawings by red lines, and marked F. rllhis receiving Aboard is placed upon a carriage with two axles' and. ifour wheels, and is made to traverse on'a railway attached te the 'side of the machine, er sustained in any other convenient manner; this carriage is made to traverse backward and forward directly under the back partjor end, of the vellum; the traversing motion may be given'to it by a crank, or by anyv gearing whichthe machinist may think best to use. Theuseof this carriage is to' receiveY the web as it falls from the vellum', and to fold it neatly and` conveniently for usel- Seventhly, we havey added, on the Vback Side of the lower lback roller on which the wire cloth or vellum revolves, a small roller lettered Gr, and marked with red ink lon the drawings; this roller is placed on bearings on the sides of the machine, a little below the center of the back roller; this small roller, G, is turned by the wire cloth, or vellum, and is so placed as to prevent the web from adhering to, and following, the vellum around, and to cause it to fall off clean upon the above described receiving board.

Eighthly, instead of the cam wheel, and

its appurtenances, as described in Thomas Blanchards specification, herein before referred to, and employed to give a lateral, vibratory motion to the hardening roller, designated by the letter H, in that specification, we have added, and use, the two levers marked H, H, in the drawings hereunto annexed. These-levers have their fulcra at 71 L, and at their upper ends they have, each, a pin attached to them which enters an eccentric groove in the hub i, by

which, as the hub is made to revolve by the whirl la, the levers vibrate on their fulcra L, 71 and, consequently, communicate the required motion to the rollers J', and j, or to either of them, as may be required.

Ninthly, we have added a small irregular board shown on the drawings in red lines and by red dots and marked I, the red dots are to denote holes which are made in the board Say three eighths of an inch in diameter this board thus perforated is placed in the inside of the vellum between the upper and lower sides of the wire cloth or vellum resting in part on, and in part inside of, a stationary box which in the original machine is placed between the upper and lower sides or inside of the saidvellum or wire cloth; the side of the board, and the member and size of the holes, must be varied according to the side of the said wire cloth vellum, and to the current or draft of air required, and all fitted to the place and position of the machine, by the judgment and skill of the workman formed on the particular case, by examining the machine under its operation, its position as' to air, the state of the atmosphere, and the materials to be used. Strips of small thin boards fastened together, or pieces of tin, sheet iron, orV any other metal, fastened together, or laid in loose; or pieces of tin, or iron, or any other metal, perforated with holes, or pipes Vperforated with holes, and the air made to pass through one or both ends for regulating the current of air, may be used for the same purpose; the object of the above board, plates, tinned ironed tube, or tubes, is to Vcause an even equable current of air to pass through the vellum or wire cloth over its wholesurface, at the same time, which causes the fur` thrown by the quick fancy, and suspended in the air to fall when it lights,` even and equably and uniformly upon the whole surface of the vellum this last operation is performed in the air chamber and when successful, as it may be easily made to be, leaves a thin even beautiful web of one uniform thickness which with little care may easily be wrought into a hat body.

Tenthly, the rollers J, J, as shown in the drawings are sometimes used in Blanchards original machine, and sometimes'not, they may be wholly omitted without any material inconvenience. The other parts of the drawings in black lines show so much of the original machine as is necessary to be shown to explain the drawings of these i1n-4 provenients which as practical hatters, by various experiments, we have been able to make.

YVe do not claim the original machine nor any of its parts as our inventions or the invention of either of us nor its combination or general arrangement. Nor do we claim the rollers levers boards or other parts which we have added separately and independently of said machine; but

We do claim as our joint invention and improvementv The severaladditions to said machine as vabove speciied in their combination and HENRY A.' WELLS. JAMES JAMES. ROBT. WV. PECK.
